Our server \\jobserver is a CIFS share > on our SAN. Is this a Rush problem, or one with the Windows stack? That's a Microsoft error; it seems the OS gave an error when rush tried to check to see if the log directory exists. Microsoft has a few links for this error; maybe one of them will help you discover the problem: http://support.microsoft.com/kb/121913 http://support.microsoft.com/kb/897089 One non-obvious cause could simply be a DNS problem; when the OS sees the UNC path \\jobserver\share1, it has to resolve "jobserver" into an IP address, and possibly that hostname resolution is being intermittent. How long has this been happening? If it's recent, does its appearance coincide with any administrative changes on the server (\\jobserver\share1) or network infrastructure? When the problem is happening, try walking up to that client (eg. "blade10", based on the above error message), and try accessing the "backslash" version of that pathname with the DIR command from a DOS window, eg: dir \\jobserver\share1\jobs\BUILDLOG ..if you get the same error, you can probably at least debug it that way. If so, I'd probably try 'ping jobserver' first, just to see if the hostname lookup is the issue (ie. see if you get a 'jobserver: Hostname lookup failure' error), and if not that, probe around with NET USE and friends to see what's up. |
